One victim said that he threw bodily fluid at her twice — once in the store and another time in the parking lot.

“It’s creepy. I think you’re in disbelief,” the victim, who didn’t want to be identified, told news station KGW-TV. “Is this really happening? It’s disgusting, who would do this? And then it goes through your mind, was he watching me this whole time?”

Detectives said there could be more victims in Oregon unaware that he attacked. Authorities in Beavertown and Milwaukie are also investigating similar incidents.

Police said that the suspect is a Hispanic male in his 20s to 40s, and are asking for the public’s help identifying him. A surveillance image of the suspect has been released from an incident on April 5.

Anyone with information about the suspect is asked to contact Portland Detective Chris Traynor at 503-823-0889.
